JAMES HENRY HEYWQOD, F RAIDCLIFFE, ENGLAND, ASSIGNOR TO CYLINDER TOP OILERS, LIMITED, '01 LEEDS, ENGLAND LUBRIGATING MEANS FOR INTERNAL-COMBUSTION ENGINES.

Application filed October 1 5, 1926, Serial No. 141,797,'and in Great Britain October 19, 1925.

This invention has reference to the lubrication of the cylinders of internal combustion engines, and has for its object to prowide an improved means or apparatus for the admission with the fuel mixture or ex plosive charges into the cylinders of such engines, of regulatedquantities of lubricant for lubricating the cylinders and the pistons operating therein, and extra air during running', and also for enabling a rich charge or ,mixture to be obtained for starting.

Apparatus in accordance with the invention comprises a lubri'cantcontaining reservoir provided with an adjustablefeed or delivery, a connection between said feed or delivery and the induction pipe or manifold of the engine, and an adjustable waive-controlled communiation between said'connection and the atmosphere, the arrangement being such that the suction of the engine draws a regulated supply of lubricant from the reservoir, and if desired, also a regulated supply of extra air, into the induct-ion pipe or manifold with the fuel mixture or ex- 5 plosive charges. The connection aforesaid is also adapted for the admission of liquid d fuel into the induction pipe .or manifold to provide a rich mixture for starting.

In the accompanying drawings Fig. 1 is a sectional elevation of one embodiment of the invention, and Fig 2 is an elevation partly in section'looking towards the right hand in Fig. 1. I Referring to the drawing, the apparatus illustrated comprises an oil reservoir 3 which is filled through an aperture normally closed by acap in which is provided a small vent opening 4. The reservoir is fitted with a sight drip feed lubricator 5 which may be of any appropriate kind. The inlet i pipe 6 of'the lubricator extends to almost the bottom of the reservoir 8 and at its upperend it is controlled by a needle valve 7 and communicates with the drip. stand pipe 8. The delivery 9 of the lubricator is connected with a union 10 which is also connected with the induction pipe or manifold of the engine by means of a pipe 11.

The union 10 is also fitted with a plug cock 12 the casing of which is provided with a cup 13.

Vhen the engine is running the suction of the engine draws oil from the reservoir 3 through the drip feed lubricator, the oil fall- By opening the cock 12 additional air may be induced in regulated amount into the induction pipe or manifold to mix with the fuel mixture, while for the purpose of providing a rich mixture for starting fuel may be drawn into the induction manifold from the cup 13.

The pipell will preferably be formed with a bend to prvent oil or fuel passing to the induction pipe or manifold except under thesuction of the engine.

What I claim as my invention and desire to secure by Letters Patent is 1-.

1. Combined means. for lubricating the pipe or cylinders of internal combustion engines and the admission of extra air during running,

comprising a lubricant-containing reservoir provided with an adjustable drip feed or delivery connected with the induction pipe or manifold, said connection having a valve controlled communication with the atmosphere, wherebythe suction of the engine is adapted to draw a regulated supply of lubmeant and, if desired, also extra air into' the cylinder or cylinders," substantially aS- herein set forth.

2. Lubricating means according to the preceding claim, characterized in that the connection between the feed or delivery from the reservoir and the induction of the engine also serves for the admission of fuel to provide a rich mixture for starting, substantially as herein set forth.

8. Lubficating means according to claim and a cock fitted to said'union, substantially as set forth. v

In witness whereof I "have hereunto set my hand.

JAMES HENRY-HEYWOOD.
